[Q] New OS update bricked my Fire. Any quick fixes?

My rooted KF got bricked by the new OS update that was released last night. It boots as normal, gets to the locker screen, and whether you unlock it or not, reboots about 15 seconds later to a screen showing the Android guy and an exclamation point in a yellow triangle. Then, if you start touching the screen, 4 buttons will show up on the side, up/down, select, and back... but they do nothing. Reboot again and it takes me to TWRP.
I know how to wipe my KF and reinstall everything, but I was hoping that someone might know of a fix for this. Especially because I just got a new computer and am still in the process of getting my normal apps installed, let alone Android SDKs that I use once in a blue moon. Plus, I have a few games that I would rather not lose my progress on.
BTW, I rooted my dad's KF the exact same way as mine and his just lost root access with the update, everything else is fine. Kinda weird.
TIA

What OS update? Your new computer will not need sdk. Also you will not escape having to wipe if something has gone amuck, unless you get lucky to be able to flash the prior system to revert the defect. You could just flash modaco http://forum.xda-developers.com/showthread.php?t=1439916 no more losing root from OTA`S. You may also get lucky and be able to flash modaco if you`re on rooted stock or previously rooted stock 6.3.1 without wiping.

About 3am last night, I found my KF bricked after just using it about 30 minutes before (the wifi was on and it was hooked up to the charger). Today, I checked on my dad's KF and he has his wifi turned off. I turned it on and it instantly rebooted to just a "command line" screen saying that it was installing an update. Took about 10 minutes and then rebooted and worked fine, except that it was unrooted. I read somewhere in the Amazon Forums today that they did roll out an update and plan on spending 2 weeks doing it to keep from bogging down their network. Granted, their Software Update page doesn't say anything about it yet.
BTW, thanks for the other info, I'll have to check it out. Sounds like I'll have to wipe it (or at least restore from a 2-3 month old backup and see how the update goes again). But that's cool that I won't need to install the Android SDK.

Explains why some are instantly being unrooted or like in your case bricked strange thing is that it doesn`t change the system version it`s still 6.3.1 figures that Amazon would pull something like this.

Hey, I did manage to find a quick fix!
In the recovery mode, I decided to try using the Fix Permissions option. Still had the same problem.
I then just used the Clear Cache option and my KF was back up and running... and still rooted.
The only issue I have found so far is that I had to change the permission to allow changing the wallpaper, just uncheck the "write" permissions, (which was probably reset by the Fix Permissions option I ran). Other than that 2 second fix, everything is fine.
Granted, I'm waiting for Amazon to do an auto-check for some file that was in the cache that told it that it had installed the latest upgrade, and since I wiped that, it may install it again. If it does, I'll post it in this thread that my quick fix didn't work. But so far so good.

It turns out that my quick fix is only a temp fix.
Twice tonight I had to clear the cache again via the recovery menu. The first time it happened, I had just finished reading and hit the power button to put it in sleep mode, which caused it to instantly reboot and then do the same thing as I mentioned above. It boots up, and within 5 second of getting the locker screen, whether you unlock it or not, it starts shutting down and reboots ending up with the screen in the attached pic (those dots are just dust that appear super bright for some weird reason because you can't see them except in the pic).
So I cleared the cache again, everything was fine, and then about an hour later I found it sitting on that screen again. Clearing the cache fixed it again, but obvious this is a reoccurring problem.
Anyone have any ideas?
I'm reluctant to do a reinstall yet because I'm afraid I'll just end up with the same problem... along with none of my apps installed.

I have the same issue my temp solution is turn off wifi asap after lock-screen appear, wait abt 1-2 minutes then I can turn on wifi and use as normal.
Everything will fine for few hours. Any permanent solution plz? I remember that it occurred after i update something from Amazon app store, maybe : apps...
Sent from my Kindle Fire using xda premium

The permanent solution is to flash another rom preferably modaco if you want the stock experience. Full wipe, your apps can all be redownloaded that is the least of your worries at this point. probably a really good time to upgrade your bootloader and recovery if you haven`t flash both of these zips as zips in twrp if are behind the curve http://forum.xda-developers.com/showpost.php?p=30780737&postcount=180 and http://forum.xda-developers.com/showthread.php?t=1632375 only get them from where I`m directing you or use smirkit http://forum.xda-developers.com/showthread.php?t=1500935.

thanks for your help. This is done with the below solution
1) Copy the update bin file to the /sdcard as update.zip
Download stock ROM : https://s3.amazonaws.com/kindle-fire-updates/update-kindle-6.3.1_D01E_4107920.bin
copy update-kindle-6.3.1_D01E_4107920.bin into Kindle Fire and re-name to update.zip
2) From the main menu of CWM, "Wipe cache from partion" to remove the existing files in the data and cache partitions
3) From the main menu of CWM, press the "Install update.zip" button to flash the stock software onto your device.
no data/application lost accept FFF and CWM

Wiping cache doesn`t remove data in twrp its factory reset that you need to concern yourself with and unfortunately there is data loss. You may have succeeded but others put themselves in a position of needing a factory cable after not properly wiping when flashing stock. This is because the data is what the kindle has a tough time handling after a complete stock flash. Flashing modaco is far safer, truth is that it will leave your recovery and bootloader intact providing a far better safety net if something were to go wrong. Also if you create a backup before you flash if something does go wrong at least you can restore a half crap backup, wipeout recovery and this is no longer possible just saying. I see far more people fail to flash stock than I ever do flashing modaco.

Thanks for the info guys.
Considering the post in the Amazon Forums said this update was being pushed out over a 2 week period, I'm just going to keep my WiFi off (unless needed) and wait until everyone should have received the update and then see how it plays out. Considering it doesn't change the software version number, I'm thinking that this update may be just targeting rooted Fires. And BTW, it appears that the post was removed, because I can't find it again. Maybe they remove any that mention rooting? I just stumbled upon it via a Google search... 99% of the question in their forum are just idiotic.
Directv used to pull this stunt all the time to bust people with hacked cards that allowed them to get all their channels for free (usually a few hours before some big PPV event). They finally completely stopped the ability to hack cards by rolling out parts of their code over a long period of time, a year or so. When the final piece was put in place, the previous parts of their code had already been integrated into the hacked card software, because it appeared safe, and along with upgrading the type of cards they used during that same period of time, pretty much eliminated the ability to cheat Directv. I'm not saying that Amazon is going to those lengths to stop people from rooting their KFs,.. but who knows? It may be costing them too much with people bricking their KFs by trying to root them. Plus, they may also be losing revenue by people getting their free apps (with ads) from the Playstore instead of Amazon. And considering they pretty much sell their Fires for cost, they definitely rely on revenue generated by buying and using things via a stock KF.
BTW, this whole issue had almost perfect timing... I was planning on wiping my KF because it definitely is slower than when I first got it (which was day 1 of its release). I've read that Gingerbread doesn't clean up after itself too well, especially not as good as ICS (kinda like a Windows registry just gets filled with junk over time, and no cleaner beats a fresh install). It also appears that the ICS roms are actually working reliably these days, compared to the last time I checked. So, in a couple weeks, I'll get to have some fun. I am a Windows/Cisco System Engineer, so this kinda stuff is fun for me.

F.Y.I.
It seems that Amazon did do a incremental update on the Original Kindle Fire version
6.3.1_user_4107720, April 30 build to 6.3.1_user_4107920, November 27 build.
I looked thru the update and the only things I found changed are to do with the
Wifi driver, launcher icons, boot animation, and boot.img; attached the changed file below.
I have not tried to update mine, will attempt this weekend.

Thank you Tera Tike for the info at least this confirms that it's not just a fluke users of rooted stock should be warned appreciate your research. I do wonder why they would change boot animation and IMG seems a bit haneous.

It seems they increased the resolution of the images in the file, but for me I can not see the difference.
For me I wonder what they changed in the WiFi driver file, tiap_drv.ko.

I took Thepooch's advice and installed MoDaCo rom on my KF. It was a snap. I had FireFireFire installed with TWRP. Just downloaded MoDaCo to PC copied to KF. Rebooted to FireFireFire Installed with Install Zip utility. Took a few minutes. Rebooted didn't loose any data , apps or functionality. Its still rooted. THANKS!

Pixel XL - HUGE data usage NOT rooted

Hey all,
I've done heaps of searching here and the wider web but only found reference to rooted phones failing to take updates.
I can't get a screenshot on here right now as I'm at work so no wifibut:
- Android OS _______________3.04GB :silly:
- Chrome__________________434MB
- Google Services ___________24.13MB
- etc
When I read about the failed update I checked in there and sure enough I have a 2017-5 patches system update sitting there failed, when I retry it it will download successfully then do step 1/2 of the installation then fail.
So it seems this would be the problem but the phone is definitely NOT rooted, any ideas??
thanks

You speak in codes, man. Could you explain your issue simpler? Right now I see an Android OS usage of 3.04GB. That seems abnormally large times 10. No one should have that, really. So it seems like your Android OS process downloaded multiple copies of system updates in error. Is that your problem?
Your post is still largely incomprehensible, so I won't make a final conclusion.
These are just suggestions:
1) If your phone is downloading system updates over and over, just damn update so it stops, or factory reset your phone.
2) If this is some kind of a rogue app, you are literally funked. Good luck trouble shooting it.
In any case, GL!

Yes, android OS used 3.04GB in ~5 days, my best guess is it was due to repeated attempts at '2017-5 patches system update'
Sorry, when I did a search I got heap of references to rooted phones having this issue so I guess I just talked from that reference point? It seemed to be a known issue but for rooted phones.
I just wanted to be clear that my issue matched those symptoms but was not rooted.
1) I've tried a manual update (many times) fails at the same point, I assume this is what is causing the data usage, as mentioned above.
2) Pretty sure it's not a rogue app
I'll try a factory reset, it's only a couple of weeks old (warranty replacement) so I hadn't really thought to reset straight away.

The phone doesn't necessarily need to be rooted to fail the update. A previously rooted phone can also fail to update as described, but typically that would mean an unlocked bootloader. I would have figured that the phone would have been reimaged and the bootloader locked on a refurbished phone, but maybe that doesn't happen. Is the bootloader unlocked? If so you could image the phone yourself to see if that works to fix it. If the bootloader is locked and a reset doesn't work, then I figure you might need to contact support about getting a different phone.
https://developers.google.com/android/images

I think you've gotten good information from everyone so far but just to add some clarity.
I had this exact same issue and was not rooted but did have an unlocked bootloader.
A factory reset did not resolve it. At the time I had issues, there were questions about rooting the stock images so I flashed PureNexus and have never looked back or had the issue again. Also, Verizon did add data to my plan and credit my account for the additional charges to negate the cost. Hope this helps!

It sounds like an issue with your phone that Pixel support might be able to help you with but they will certainly suggest a factory reset so you should do that first. Since you have a refurbished phone you don't know how the previous owner was using it and its possible a modification he made is still on the phone and causing you problems. If the failed system update isn't actually causing the excess data usage it could also be a carrier issue. I know some Project Fi users had that problem and it was related to the service. Google gave people credit for the excess data. You could also have an app that is interfering with the update so a factory reset should definitely be your first step and I'm guessing it's fairly likely to fix your problem.

Note 4 Help After Update

So, here's the basics:
AT&T Note 4, Official. Never had issues, never needed to root...
Build MMB29M.N910AUCS2EQF1
June 1, 2017 Security Patch Update
6.0.1
All updates have always come OTA.
Here's the issue:
When the MAY security update come out, I updated like I always do. Since then, my phone started locking up, randomly rebooting, all around pissing me off
I read about having Samsung Experience in Best Buy reapply the update, but our Best Buy no longer has Samsung.
So I went to AT&T to see if they had capacity to do it, nope; just a moron sales-boy who was clueless, just wanted me to pay $225 for my deductible and get an S8 (maybe if they offered the + I might have).
Went to a third party mobile repair and they quoted $35 up front but didn't guarantee they'd be able to 'find the update cause they're in China' (true story).
I've uninstalled apps and reinstalled systematically trying to find a culprit (to no avail).
Tried using Kies and Smart Switch and they both error when I enter the model and serial.
I did a factory reset from recovery and wiped caches, but the problem persisted.
So I installed Wake Lock (darken) and that seemed to tide it and 'cure' the problem.
June security update come out and I installed it. I had to remove and re-seat batteries, restart, pray to my fictitious gods and finally it got to the green App Optimizing and finished.
I removed the wake lock but the problems persisted; so I reinstalled it and that's currently where I am...
I have close to 20 years with computers, but am total n00b with Android.
I see there are the security updates here and downloaded the May and June.
At this point, would applying back to the May update have the possibility of helping even though I've now installed the June?
If so, how? I read you copy it to the root of an SD Card and apply update through the recovery screen, is this correct?
Should I factory reset/wipe caches before re-applying the update?
If I need to re-image the phone (another possible fix I read), what file do I need to use to go about doing that?
At this point, I'd like to A) limp by til the Note 8 comes out and B) get this back up and running so my kids can inherit it for their games when I get the 8...
Any help or direction would be greatly appreciated.
(Just noticed this might be more appropriate in the Help section. Mods, please feel free to move this to the correct sub-section. I can't find a way to delete the post and repost it there...)

General December update woes...

The past few years, I usually install the ota manually on my pixels if they don't come right away on my phone (they usually do in CA). I keep my bootloader unlocked (just in case things go haywire) but haven't modified or rooted in many years. So today, because the update was so large (more reasoning below), I decided to flash the factory image and remove the "-w" command so it wouldn't wipe the phone. Done this many times.
So my usual process is to flash both slots one after the other. I flashed the current slot it was on (b) then switched to the (a) slot. Been doing the same since Android 4 (and A9 for a/b slots), hundreds of times. After flashing slot (a), it restarted like it's supposed to. I then get the dreaded "Your device is corrupt" message. First time I've seen this on any of my 4 Nexus and 5 Pixel phones. Okay so I decided to try flash it again, this time with the wipe command (recovery wouldn't work, same message). Flashing completes, same message. Then tried the flash.android.com - flashed all slots, wiped options on - same thing. The " pixelrepair.withgoogle.com " website doesn't recognize the phone which is odd because flash.android.com does. I tried flashing the original image from November and 2 other build versions. Still no go.
Not sure what happened here. I don't think anything is wrong with the latest image. The reason I flashed this image was because I had a thought today - does flashing the "ota zip" update the bootloader and other firmware versions (they were different different versions this update). So I guess my curiosity killed the cat ... I should have just ran the ota first to see if the bootloader/radio versions updated, but of course the ota updates them (or they would never get updated otherwise). Ahh well. Now I will have to deal with the silly carrier warranty circus.
Also - I never thought an update could cause a phone to completely corrupt itself where it can't be fixed by the user. All of these posts on xda/red_dit etc over the years - I really didn't think it was possible. I always thought corruption must have been there before, but now I'm not so sure.
update: flashed the last build from November using flash.android.com and was able to get my system back. 2nd flash for that build worked.

If anyone has any fastboot tricks - I'd try anything at this point.

You're trying to flash with fastboot right? Use that Android flash tool. You'll see a link to it in the factory image page. I went through the same thing you did, I got the corrupt device. at the very end It'll ask you to Lock the bootloader just don't do it if you want to stay unlocked.

Oh maybe I misunderstood you tried that and it's not recognizing it

flash.android.com recognizes it and it completes but the corrupt message still appears.
I'm going to try the original build from October, using the flash.android.com website - and pick all the Advanced Options, see how it goes (disable verity and verification, force debuggable and flash all partitions). I guess it's worth a try. pixelrepair website doesn't recognize the phone.

ok what the hell. what a mess. it was weird, long-pressing the power button would never restart the device. it took multiple tries. I've learned over the years to remove the case because it can hinder the restart sequence. But even just getting into fastboot was difficult.
Anyhow it looks like I'm back.
2nd time flashing this exact image, but this time it worked - I used the flash tool website and flashed the November SD1A.210817.037 (non vzw build). I just chose options "All Partitions, and full wipe"(my next step was to try disabling verity and debugging but this worked).
a few reports on red_dit of corruption on the 6 Pros. hopefully Google pulls it soon. if people don't have the "oem unlocking" option enabled, their toast.

That's what can happen when we're inpatient and not willing to wait for the right version to actually push to the device.

seriously? the right version? I installed the right version, and others also had the same issue just by updating normally through Android interface.
you shouldn't be able to "corrupt a system" just by updating to the official update build. this isn't 2012... anyway, I mostly posted and updated for others who might have had issues also.

Well in the 4 years of me being on Android I've never had it happen.

I literally just got my Pixel 6 Pro and attempted the December update and got a firmware corrupt. The only options is try again or factory reset. I just finished going through the first time setup and already got this.

Why not just adb sideload the OTA image, rather then flashing on both slots the factory image? It just sounds a bit of a hassle to me.
I know, I used to fastboot flash without -w my nexuses as well, but that was before the OTA images were available.

yeah it's super rare. been flashing images and ota's since Nexus 4. But it happens.
I usually get the updates right away but sometimes I'll update the ota. I usually reflash the factory image every year after the beta. just seems odd how it corrupted the device. couldn't get into the system at all (or recovery/rescue modes).

apparantly it has something to do with Bluetooth? I don't know how, but if you can get into safe mode and disable Bluetooth, clear cache/data for it and update all your google service apps, it can fix it (keeping Bluetooth off while restarting phone in regular mode) - but I couldn't load Android.
The trick to getting into Safe Mode is this: Turn off the device. Hold down power and and as soon as you see the "G" Logo, hold volume down. it will directly boot you to Safe mode. cool little trick. you'll have to manually enable wifi because it gets turned off.
At this point, if you can, enable OEM Unlocking. at least you'll be able to save the device if anything serious happens (like what I went through). the pixel repair website also works but I couldn't get into "Rescue Mode"

Question February Update caused my phone to reboot all the time

Had absolutely no issues with my Pixel 6 Pro on the January update but as soon as I installed the February update my phone reboots so much when the screen is off. When I'm using it, there are no issues. The second I turn off the screen, it reboots. Then it'll reboot 5 more times before I can even unlock my phone. Then I'll turn the screen off and it'll reboot again. It must have rebooted around 500 times last night.
Is there a fix for this? Or a step by step guide on how to install the January update over the February one?

I don't think you need a unlocked bootloader to sideload just USB debugging enabled if you wanted to try a full wipe. Maybe try factory reseting from settings - I'm going on the assumption that the bootloader isn't unlocked

Had absolutely no issues with my Pixel 6 Pro on the January update but as soon as I installed the February update my phone reboots so much when the screen is off. When I'm using it, there are no issues. The second I turn off the screen, it reboots. Then it'll reboot 5 more times before I can even unlock my phone. Then I'll turn the screen off and it'll reboot again. It must have rebooted around 500 times last night.
Is there a fix for this? Or a step by step guide on how to install the January update over the February one?

You can't downgrade once you've upgraded. It's best if you backup your data and try starting fresh on the February build to see if it causes any issues.
Use the flash tool and make sure both partitions are formatted and try again.
Did you do any modifications to your phone that could have caused the random reboots?

That's correct, it isn't unlocked.

I have done absolutely no modifications other than typical downloading of apps and modifying through there but even that is just theming. By "try again," just wipe and then reinstall the update?

The random reboot bug seems to be a problem with Android 12. I haven't yet seen any clues as to the reason why.
Sometimes it's caused by a backup, sometimes by an update, some claim it's because of a hardware failure.
I experienced the same when I got my Pixel 6 Pro out of the box - about 2 random reboots per day, I had to get a replacement device to fix that.
My Pixel 3 also has the random reboot problem right after I updated it to Android 12, just like you said - every couple minutes, even though it reboots BOTH when in active usage AND when the screen is off. I have not yet tinkered with the device to find the reason, since I don't need that phone (anymore).

As a last resort, if you don't want to lose data on reseting the device, my advice would be to:
Download the latest OTA to your PC & sideload it in recovery mode (hold vol down before screen comes on, upon reboot). That will re-flash all important blocks & will boot you from the opposite partition (A/B) but keep your data/apps, hopefully fixing whatever the issue is in the process.

I'd be happy with 2 random reboots per day. Not even kidding, I must be at 100 a day. It's super random too. None from 9 am until around 1pm and then all of a sudden 10 in a row.
I'm pretty sure it's a software issue, had no random reboots before I installed the February update. Will probably try reformatting the entire phone first and see how that goes.

Thanks, will try this out if a reformat doesn't work.

Try safe mode and see if it still happens.

Still happened in safe mode.

I would honestly try a complete wipe and fresh install of the OS to see if it still happens. If it does you could get it RMAd since it could be hardware related.

By "wipe and fresh install" do you mean reformatting it normally through the phone (like if I was returning a used phone)? Or is it as Daniel suggested above?
